Lining local deformation crack monitoring device based on water conservancy project

Abstract

The invention provides a lining local deformation crack monitoring device based on a water conservancy project, and relates to the technical field of lining local deformation crack monitoring, the lining local deformation crack monitoring device comprises a mounting seat, a display block is rotatably mounted in a rotating cavity, the display block is of an annular block structure, a rotating block is fixedly mounted on the bottom end face of the display block through a connecting piece, and the rotating block is of a hollow structure; the connecting piece is of a cylindrical structure, the connecting piece is rotationally connected into the communicating groove, the rotating block is of a circular block structure, the rotating block is rotationally connected into the rotating groove, and the connecting piece is provided with an identification structure, so that a manager can conveniently check whether a worker inspects the crack every day according to regulations; the method plays a forced role in checking the crack by the staff according to the regulations every day, and solves the problems that an existing observation identifier only has an identification function and cannot play an identification function, so that a manager cannot identify whether the staff checks the crack according to the regulations every day or not, and application defects exist.

Description

technical field [0001] The invention relates to the technical field of monitoring local deformation cracks of lining, in particular to a monitoring device for local deformation cracks of lining based on hydraulic engineering. Background technique [0002] Lining refers to a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. [0003] When cracks appear in the local deformation of the lining, it is generally necessary to select a representative position to embed an observation mark at the crack, and to check it every day according to the regulations. The management personnel cannot identify whether the staff have inspected the cracks every day as required, and there are application defects. Contents of the invention [0004] In view of this, the present invention provides a monitoring device for local deformation cracks in linings based...
